THRAsHlNc-MACHINE.

SPECIFICATION forming part of Letters Patent No. 518,689, dated January 30, 1894. Applicationiiled September 7,1892. Serial No. 445,289. (No model.)

The object of my improvements is to pro.

vide a method of, and means for allaying the dust caused by the operation of a thrashing machine upon the grain fed therein; and to various peculiarities of construction and operation hereinafter fully described and claimed.'

As is well known, the grain fed to thrashing machines gives forth'in the operation of thrashing a large quantity of dust and fine particles of straw which, floating in the airin every direction, cause the operation of the machine to be particularly annoying to anybody in that vicinity. The dust and ne particles of straw insert themselves into the clothing and lungs of themen operating the machine and tend to serious lung troubles as Well as annoyance. I propose to do away withV this troublesome and dangerous dust, by prov1d1ng a Jet or jets of steam or other moistening means which increase the specific gravity` of the dust and other particles and effect the deposit of the same upon the strawfor else- Where, instead of blowing about in the vicinity of the machine. I have illustrated one method of doing this in the accompanying drawings, on which like reference letters indicate corresponding parts and wherein- Figure l, represents a perspective View of a thrashing machine with one side removed and my improvements applied thereto; Fig. 2, a plan view of the same; Fig. 3, a detail view of the jointed pipe connection; Fig. 4, a similar view to Fig. 3, showing the pipe folded; Fig. 5, an enlarged view in section,of the joint between two sections of the pipe, and Fig. 6, a fragmentary View showing the sprayers for water.

The letter A, designates the casing of a thrashing machine of any suitable style in ordinary use to which my improvements may be applied. The grain is fed into the machine from the table B, underthe revolving spiked cylinder C, located above the cylinder concave Dfrom which the straw passes along over the vibrating or agitating fingers E, while the grain is separated through the screeners F, and falls into the conveyer G. The grain Ykernels naturally seek the lower level after separation from the strawwhichis superposed, as they travel onward from the cylinder. The amount of moistening fluid is regulated according to the quantity of dust, and the straw shields the kernels to a great extent, so as not to unduly wet the latter. The chaff and ine particles are blown out by the blower H. Within or near the casing is mounted my device in any convenient position, but preferably as shown in Figs. l and 2. It consists of pipes I, I, or other conductors, transversely or otherwise disposed within said casing, and providedA with nozzles orother discharge openings through which the moistening means is discharged. Either steam or Water may be used, the pipes I, I, being connected by a jointed pipe, hose, or other conductor, J, with a steam boiler K, or other source of supply and providedwith a valve L, adjacent to the feeding table to regulate or shut off the supply of steam, or other fluids, to such perforated pipes I. The steam contacts with the dust and Heating particles of straw, and effects their deposit upon the straw delivered from the thrasher, or so increases their gravity as to prevent their flying far after their delivery from the machine. 'Ihe grain being below the straw, escapes contamination by the moistened dust and other particles. The jets from the perforated pipes I, which act as sprinklers, are directed outward in the direction of the straw as shown in Fig. 1.

It may be desired to use water instead of steam and Fig. 6, illustrates a sprinkler having spraying nozzles M, delivering an evenly comminuted spray of water upon and into the outgoing straw.

These machines being adapted to travel froml place to place require a jointed pipe connection with the boiler or other source of supply, and I have shown such pipe connec- ICO i tion in Figs. 3 to 5, consisting of sections jointed together at O, and alternately disposed asin Fig. 3, so as to allowr of being compactly folded as shown in Fig. 4. The joint 5 is shown in detail in Fig. 5, and consists of a tapered piece P, fitting into a corresponding socket P', the former having a shoulder engaged by a screw threaded collar Q, to maintain it in coupled position. The pipe connec- Io tion may thus have any amount of playin one direction and the length of the joint renders it less liable to breakage than if the section were directly connected by a comparatively short joint.

I wish to be understood as laying claim broadly to this' means for doing away with the annoyance of the light Iioating particles of dust and straw and eecting the deposit of the same. Furthermore I claim the means zo for accomplishing the above mentioned object irrespective ot the location of the same in any particular part of the machine though the position illustrated is the preferred one. I do not therefore limit myself to the exact means herein shown and described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the chambered 3o body of a thrashing machine having thrashing, separating, and feeding mechanism to act on the grain kernels and superposed straw passing through the machine, of spraying devices adapted to spraya moistening duid upon the passing straw and ioating particles within the chamber of the machine, substantially as and for the purpose described.

2. The combination with a thrashing machine having a casing forming a chamber for the grain acted on, ot interiorly mounted 4o spraying devices consisting of transversely mounted pipes provided with openings adapted to spray the moistening liuid delivered to the pipes, into the oating particles of dust and straw within the chamber and eect their deposit on the straw, and means to supply said moistening iiuid to said pipes, whereby the straw leaves the machine, carrying with it the dust and particles deposited thereon. 5o

3. The combination with a thrashing machine having a casinginclosing the thrashing and separating mechanism, of a spraying device consisting of lon gitudiual and transverse pipes, thelatterprovided with openings adapt 55 ed to deliver jets of steam about within the said casing to deposit the dust and straw particles upon the straw as it passes outward, a steam boiler and connecting pipes between said boiler and spraying device, and a regu- 6c lating valve for said pipe to control the quantity of steam, substantially as and for the purpose.

In testimony whereof I aix my signature in presence of two witnesses.

DAVID B. TANGER.
